Saw this in case it’s of help: https://wpdevelopment.courses/articles/how-to-fix-activatemode-is-not-a-function-error-in-gutenberg/

I am also having this issue too. It seems to be in fine in Chrome for me, but Firefox it shows nothing in the TinyMCE iframe. The body/head of the iframe is blank.

Only relevant in the console says: MouseEvent.mozPressure is deprecated. Use PointerEvent.pressure instead at wp-tinymce.js 3:8856

I’m also using Advanced Custom Fields so not sure if it’s something between the two.

EDIT: Installing the “Enable jQuery Migrate Helper” as listed in the stickied thread seem to fix it in Firefox. Not sure if that is the best solution going forward but it’s a start.
